i fyou hard coded the exec command and it works in a browser, then you
need to print out the dynamically generated command, and check that
the two are equal. My guess is that they aren't! For instance it would
be my guess that in your line above, the dynamically generated line
loses the "" around some paths and the call is broken there, and
fails.
You could try adding &2>1 in order to divert the errors to stdout to
see what the actual eror returned is.
Heres the way I would do it:
//assuming that "ogr2ogr-f" is a program name and that -f isnt an
argument.
//using single forward slashes which windows understnads just as well.
//using single quotes because you dont need php to parse for special
whitespace characters like \r or \n
$var1 = 'C:/Program Files/FWTools/ogr2ogr-f';
$var2 = 'MapInfo File';
//assuming f: is not a mapped or network drive
$var3 = 'f:/out2.mif';
$var4 = 'f:/tgr24001/tgr24001cty00.shp';
//any var that _might_ have spaces in it should be escaped
//overkill but it will escape all paths, so if there _are_ spaces
things will work
$command = '"'.$var1.'" "'.$var2.'" "'.$var3.'" "'.$var4.'"';
exec( $command );
